Abstract

Jersey and Limousin non-lactating cows were sampled at two different seasons to determine the beta-carotene
concentration and fatty acid profiles of subcutaneous adipose tissue. Results demonstrate significant differences between the Jerseys and Limousins in the concentration of beta-carotene and 14:1, 16:0, 18:1(w-7) and 18:3(w-6) fatty acids. Seasonal variations did not affect beta-carotene concentration but had a major effect on most fatty acids and ratios of fatty acid groups. There was no correlation between beta-carotene concentration and individual fatty acids which may indicate that there is no direct effect of beta-carotene on fatty acid metabolism.
